Tenofovir alafenamide (TAF), a prodrug of the nucleotide analogue tenofovir (TFV), is an antiretroviral (ARV) agent approved either as a complete regimen (elvitegravir/cobicistat/emtricitabine (F)/tenofovir alafenamide (TAF), rilpivirine/F/TAF, bictegravir/F/TAF), or for use with other ARVs (F/TAF), for treatment of HIV. TAF is a substrate of P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP) transporters. Disposition of TAF may be altered by co-medications that can inhibit or induce P-gp or BCRP transporters. The effects of ARVs on the pharmacokinetics (PK) of TAF were evaluated in 3 studies.

Inhibitor or Reverse Transcriptases or of RNA-dIrected DNA polymerase.
Agents that aid or increase the action of the principle drug (DRUG SYNERGISM) or that affect the absorption, mechanism of action, metabolism, or excretion of the primary drug (PHARMACOKINETICS) in such a way as to enhance its effects.
Reverse transcriptase (RT) is an enzyme used to generate complementary DNA (cDNA) from an RNA template, a process termed reverse transcription. It is mainly associated with retroviruses. RT inhibitors are widely used as antiretroviral drugs. RT activitie...
